SCREEN PRINTING APPARATUS AND KEY BOARD WITH KEY TOP PRINTED BY SCREEN PRINTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a printing apparatus which can substantially prevent a relative movement of a movably arranged key top on the underside of a screen to the screen from being generated when a squeegee slides on the top face of the screen. SOLUTION: The underside 24 of the screen 20 has a holding body 26 having a holding face 27 coinciding with at least a part of a contour, namely, four sides of the key top face 29 which the key top 28 has and fixed and projected on the outside of a contour of a key top face 29. It is possible thereby to prevent the key top 28 from relatively moving to the screen 20 while the squeegee 54 slides on the top face 23 of the screen. COPYRIGHT: (C)2004,JPO&NCIPI
